The tax credit lowers what you pay for health insurance each month, not just at tax time

The Premium Tax Credit under the Affordable Care Act (ACA) reduces your monthly health insurance bill directly. You do not wait until April to see the benefit — the credit goes to your insurance company on your behalf, and your monthly premium is already lower when you enroll. The amount depends on your household income and the cost of the second-cheapest Silver plan in your area.

The credit works like this: the government calculates what a certain percentage of your income should go toward insurance (the percentage varies by income level). If the cheapest plan available costs more than that percentage, you get a credit to make up the difference. If your income is lower, the percentage is lower, so the credit is larger.

You can receive the credit in advance — meaning your insurer gets paid before the year ends — or you can claim it when you file taxes the following year. Most people use the advance method because it makes premiums affordable right away.

Key Takeaways

  • The Premium Tax Credit reduces your monthly insurance payment based on your household income and the cost of plans in your area.
  • You can receive the credit in advance each month, or claim the full amount when you file your tax return the following year.
  • If your actual income differs from what you reported when you enrolled, you may owe money back or receive a refund when you file taxes.
  • You must enroll through Healthcare.gov or your state's health insurance marketplace to receive the credit — private insurance bought outside the marketplace does not may have access to.
  • The credit is available to people earning between 100% and 400% of the federal poverty level, though some states have expanded the range.

How the credit amount is calculated based on your income

The government uses a formula that ties the credit to your household income. First, your income is compared to the federal poverty level for your household size. If you earn between 100% and 400% of that level, you may receive a credit.

The formula sets a target: a percentage of your income that you are expected to contribute toward insurance. At 100% of poverty, that percentage is roughly 2% of income. At 400% of poverty, it rises to about 9.5%. The exact percentages change each year. If the second-cheapest Silver plan in your area costs more than your target amount, the credit covers the difference.

For example, if you earn $30,000 per year and the second-cheapest Silver plan costs $350 per month, but the formula says you should pay $200 per month, the credit would be $150. That $150 goes to your insurer each month, so your bill is $200 instead of $350.

Advance credit versus claiming it on your tax return

When you enroll in a plan through Healthcare.gov or your state marketplace, you choose how to receive the credit. Most people select advance credit, which means the government sends the money to your insurer before the year ends. Your monthly premium is already reduced.

If you choose not to take the advance credit, you can claim the full credit on your tax return the following year. This means you pay the full premium each month, then get a refund (or a credit against taxes owed) when you file. This route makes sense only if you expect your income to drop during the year or if you want to avoid reconciliation issues.

Most people use advance credit because it makes insurance affordable when ready. However, you must report income changes to the marketplace if they happen — if you do not, you may owe money back at tax time.

What happens if your income changes during the year

If you receive advance credit and your actual income ends up different from what you reported when you enrolled, you will reconcile the difference on your tax return. The marketplace asks you to report major changes — a job loss, a raise, marriage, or a new child — but changes are not always reported right away.

If your income was lower than you reported, you may have received less credit than you were may have access to to. When you file taxes, you will get a refund for the extra amount you should have received. If your income was higher, you may have received more credit than allowed. You will owe the overage back, though there are limits on how much you have to repay depending on your income level.

This is why keeping records of income changes and updating the marketplace when they happen matters. It prevents a large bill or a smaller refund at tax time.

The difference between the Premium Tax Credit and the Cost-Sharing Reduction

The Premium Tax Credit and the Cost-Sharing Reduction (CSR) are two separate benefits, though they work together. The Premium Tax Credit lowers your monthly premium. The Cost-Sharing Reduction lowers your deductible, copayments, and coinsurance — the money you pay when you actually use care.

To receive the Cost-Sharing Reduction, you must enroll in a Silver plan and have income between 100% and 250% of the federal poverty level. The reduction is automatic if you meet the income threshold — you do not choose it separately. A Silver plan with CSR has a much lower deductible than the same plan without it, even though the premium may be similar.

Many people focus only on the premium credit and miss the CSR, which can save thousands in out-of-pocket costs. If your income is low enough, choosing a Silver plan unlocks both benefits.

Who is not may be able to access for the tax credit

You must enroll through Healthcare.gov, your state's ACA marketplace, or a federally supported marketplace to receive the credit. If you buy insurance directly from an insurer or through a broker outside the marketplace, you cannot claim the credit, even if you meet the income requirements.

You also must be a U.S. citizen or a lawfully present immigrant. Undocumented immigrants are not may be able to access. If you have access to affordable employer health insurance, you may not be may be able to access for the credit, though the definition of "affordable" is specific — it means the employee premium does not exceed about 9.5% of household income.

If your income is below 100% of the federal poverty level, you do not may have access to for the credit in most states. However, some states have expanded Medicaid to cover people in this income range, which may be a better option.

How to report the credit on your tax return

If you received advance credit, you will report it on Form 8962 when you file your tax return. This form reconciles the credit you received with the credit you were actually may have access to to based on your final income for the year.

You will also receive Form 1095-B from your insurer, which shows the months you had coverage. This form is informational and helps you complete Form 8962. Keep records of any income changes you reported to the marketplace during the year, as these affect the calculation.

If you did not take advance credit and are claiming the credit for the first time on your return, you will also use Form 8962 to calculate the amount. A tax professional or free tax preparation service can help you complete these forms correctly.

Frequently Asked Questions

Can I get the tax credit if I am self-employed?

Yes. Self-employed people report their income on Schedule C and use that net income to determine credit may be able to access. You must enroll through the marketplace to receive the credit. If your income fluctuates, you can update the marketplace when it changes to adjust your credit amount.

What if I do not file a tax return?

If you received advance credit, you must file a tax return to reconcile it, even if your income is too low to normally require filing. If you do not file, you cannot claim any refund you may be owed, and the IRS may contact you about the unreported credit.

Does the tax credit count as income for other programs?

No. The Premium Tax Credit itself is not counted as income for purposes of other means-tested programs like SNAP or housing information. However, the income you use to calculate the credit is counted, so your may be able to access for other programs depends on your actual income, not the credit amount.

Can I switch plans during the year and keep my credit?

Yes. Your credit follows you to any plan you enroll in through the marketplace. If you switch to a more expensive plan, your credit stays the same, so your premium goes up. If you switch to a cheaper plan, your premium goes down, but your credit does not increase — the savings go to you.

What happens to my credit if I move to a different state?

You will need to enroll in your new state's marketplace and report the move. Your credit will be recalculated based on the plans available in your new state and your current income. Some states have different marketplace rules, so contact the new state's marketplace for enrollment instructions.
